Using the principle of direct variation, the solution to the problem given are :
5 miles per hour d = 5t15 miles 4 hoursGiven the Parameters :
Distance = d
Amount of time = t
d α t ; d = kt
We can find k = constant of proportionality = speed of travel ;
d = 10 miles ; t = 2 hours
10 = 2k
k = 10/2
k = 5
Hence, speed = 5 miles per hour
B.) The direct linear variation expression becomes ;
d = 5t
C.) Distance traveled in 3 hours :
t = 3 hours
d = 5t
d = 5(3) = 15 miles
D. Time taken to travel a distance of 20 miles
d = 5t
20 = 5t
t = 20/5
t = 4 hours
Therefore, it will take 4 hours to travel a distance of 20 miles.

The answers are :
a) The graph is translated downwards by 4 units.
b) The graph is translated downwards by 2 units.
What do you mean by translation of a graph ?
The modification of an existing graph or graphed equation to create a different version of the following graph is known as translation.
a)
The graph of y = f(x) is shown.
The other function is y = f(x) - 4.
As it can be observed that the graph is translated from its parent function which is y = f(x) to function y = f(x) - 4.
The graph is shifted down by 4 units or translated downwards by 4 units.
b)
Here , the graph of y = g(x) is shown.
The other function is y = g(x -2)
As we can observe that the graph is translated from its parent function which is y = g(x) to function y = g(x - 2).
The graph is shifted downwards by 2 units or translated downwards by 2 units.
Therefore , the answers are :
a) The graph is translated downwards by 4 units.
b) The graph is translated downwards by 2 units.

What is the primary difference between exponential and linear functions?
A: The growth of an exponential function is proportional to the previous growth while the growth of a linear function is constant.
B:The growth of a linear function is proportional to the previous growth while the growth of an exponential
function is constant.
C:The growth of a linear function is proportional to the previous growth while the growth of an exponential
function is proportional to the quadratic growth.
D:The growth of an exponential function is proportional to the quadratic growth while the growth of a linear function is constant.
Answer:
A
Step-by-step explanation:
We know that the growth of a linear function will always be constant. So, that eliminates B and C.
A quadratic function can be a function such as [tex]x^2[/tex], or [tex]5x^2+7x[/tex], etc.
An exponential function wouldn't be [tex]x^2[/tex], it would be [tex]2^x[/tex]! Or [tex]3^x[/tex], or [tex](1.738283)^x[/tex], etc. Therefore, D is eliminated.
So, the answer is [tex]\boxed{A}[/tex] and we're done!
